Porter's marriage at the end of 2009 to her long-term partner, fellow-comedian Justin Edwards, led to a substantial re-write of her successful 2009 Edinburgh Festival Fringe show Fool's Gold for her 2010 UK tour. In the original script, Lucy claimed she was unlikely to ever marry because of an "allergy to gold", meaning she would never be able to put on a wedding ring; on tour, she made self-deprecating reference to the original material, given that she was then married.[10]

Porter presented FirstPlay, a weekly digital "magazine" for European customers on the PlayStation 3. She hosts the successor show, Access, which is still available weekly on the PlayStation Network.

Porter created Screaming with Laughter, an afternoon mother and baby comedy club. The club tours the country to play for parents with infants under a year old.[11]

In 2014, Porter wrote her debut stage play, The Fair Intellectual Club, which premièred at the Edinburgh Festival Fringe at the Assembly Rooms, directed by Marilyn Imrie. Porter developed this into a comedy series of the same name for BBC Radio 4, featuring much of the same cast and also directed by Imrie.[12] Porter has since expressed[to whom?] a desire to write more plays for the Festival in the future.
